Avalanche Forecast

Poor - Due to the number and quality of field observations

On Thursday, expect mostly cloudy conditions with light scattered flurries. Freezing levels should be near valley bottom with light-to-moderate NW wind in the alpine. The next storm system is expected to reach the coast on Friday morning but it doesn't look like much precipitation will make it into the interior. Friday may see 2-4mm of precipitation with freezing levels around valley bottom and light-to-moderate SW wind in the alpine. Saturday may see another 3-6mm with temperatures remaining cold and alpine winds easing.

On Tuesday we received a report of a size 1.5 skier remotely triggered avalanche in the far north of the region. It released on a steep, wind loaded feature and was triggered from 5m away.  The slab was 25-45cm thick and occurred around 1600m elevation. On Sunday we received a report from the Hankin area of a natural size 1 slab avalanche. This occurred on a north aspect at treeline. The crown depth was around 20cm and it failed on the most recent rain crust. Check out the report here: http://goo.gl/WdmvxL

Since Friday, the region has received around 30-50cm of new snow. Strong winds have created wind slabs in exposed terrain and have probably striped the snow off of exposed slopes. Below the new snow you'll likely find old wind-scoured surfaces or old wind slabs in exposed terrain, and settled storm snow closer to treeline. Near the base of the snowpack, weaknesses such as the mid-November crust-facet layer are still of concern. We don't know much about this layer but older reports suggest that it may still be reactive in isolated areas.
